■ Water Distribution System
Multiple choices of piping connection options—single inlet, dual inlet, top, side or bottom inlet, side outlet or
bottom outlet—designed to have the right connections for your application.
Gravity flow distribution system—allows easy, nonrestrictive maintenance. Basin covers are standard.
Marley Spiral Target polypropylene nozzles—delivers precise distribution of water over the fill area.
Marley MX thermoformed PVC film fill—suspended from structural steel tubing. Integral louvers keep
circulating water confined to fill, even at low air rates.
Drift Eliminators—limit drift losses to no more than .005% of the design L/s flow rate.
■ Structure
Crossflow configuration—provides easier and safer maintenance.
Series 300 stainless steel or G600 galvanized steel construction.
Factory assembled—ensures final field installation will be hassle-free.
Two large access doors—provides nonconfining, quick visual inspection of cold water basin,
internal structure, drift eliminators and mechanical equipment in the plenum area.
■ Air Movement Package
Removable fan guard—welded heavy gauge rods. Hot dip galvanized after fabrication.
Eased inlet fan cylinder—ensures full area, low turbulent airflow through the cylinder.
High efficiency fan—wide-chord design for maximum efficiency at low fan tip speeds.
Marley System 5 Geareducer ® drive—requires no oil changes for five full years. Offers significant savings
in maintenance costs. Marley SofTork ™ coupling absorbs excessive shock loads at start-up.
Marley PowerBelt ™ drive (limited current availablity)—all aluminum sheaves, easy belt replacement and
40,000-hour bearing life.
TEFC Fan Motor—1.15 service factor, variable torque, and specially insulated for cooling tower duty.
The NC Class air movement package including the structural support—guaranteed against failure for a
period of five full years. The motor is warranted separately by the motor manufacturer.
